The package.json poses as an npm staged-publishing placeholder (`\"stub\": true`, \"Temporary package placeholder for staged publishing\"). Published by npm account `newtestnewdont` on 2026-10-21 after a benign 1.0.0; the same account published benign-looking color-utils-testmetest, string-helpers-testmetest and byte-stride-testmetest. 0.0.2 (published 3.5 hours after 0.0.1) is the same loader and hook with a re-encrypted, additionally obfuscated payload.\n\n---\n_-= Per source details.

The binding.gyp here declares target type 'none' with no C/C++ sources and abuses GYP command-expansion `<!(env node index.js...; echo stub.c)` to execute index.js at install time. index.js is a Caesar-cipher/charcode-obfuscated loader wrapped in eval that AES-128-GCM-decrypts a 319 KB sibling blob (data.bin) using hex key/iv/aad hardcoded in the loader, brotli-decompresses the result, writes it into a mkdtemp'd `.b-<rand>` directory, and spawns the Bun runtime (declared as an npm dependency `bun ^1.2.18`) to execute the dropped file, bypassing Node-based inspection. package.json sets `stub: true` with description 'Temporary package placeholder for staged publishing' and the README claims a holding version, yet the tarball ships the obfuscated loader, the encrypted blob, the binding.gyp install hook, and the alternate runtime — the stated purpose contradicts the shipped behavior. The actual payload bytes are not inspectable statically; the combination of install-time execution, multi-layer obfuscation, hardcoded-key AES-encrypted blob, drop-to-temp, and alternate-runtime execution matches the npm alternate-runtime dropper pattern.\n","state":0,"publishedAt":"2026-10-21T18:00:00+00:00","modifiedAt":"2026-10-22T06:45:05.7864498+00:00","affected":[{"ecosystem":"npm","name":"pixel-map-testmetest","ranges":[],"versions":["0.0.1","0.0.2","0.0.3"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/pixel-map-testmetest/v/0.0.1","https://www.npmjs.com/package/pixel-map-testmetest/v/0.0.2","https://www.npmjs.com/package/pixel-map-testmetest/v/0.0.3"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-18180","license":"OSV · upstream source license applies","key":"osv:MAL-2026-18180","identifiers":["MAL-2026-18180"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
